Pierce Johnson with a perfect inning. I'm pretty interested to see how he might do in relief, if he can stay healthy. Might be a pleasant surprise this year.

He mentioned in an interview that Bosio suggested an adjustment that he says has really helped him and has clicked. And said he's liked relief, not pacing himself. (He didn't say it, but I assume not trying to mix in inferior 3rd and 4th pitches must also be a factor.)

Barring some serious injury or unanticipated regression from a position player, if Russell has the kind of improvement he and the team seem to expect, Baez has reasonable improvement at the plate, Schwarber is available for a full season without a serious decline from what he did in 2015, and Heyward comes close to resembling the pre-2016 Heyward, the 2017 Cubs could be a major offensive force.
